The heel-plate is made with a hole of same size of bolt-head, and thesnath-stick is counterbored to receive the bolt-head after passingthrough the plate, and also bored to receive the shank of bolt. Thefriction caused by drawing the bolt head into the seat thus formed forit by means of the nut N holds it firmly in any desired position.
